As shown in Figs. 1' to 3 inclusive which illustrate oneembodiment ofthe invention, my improved rivet placing deviceiis providedA withv an elongated hollow member or tubeV I0v which forms a support orv magazine adapted tocontain aplurality of vrivets II orv other-larticles to'be fed. The tube I0 is open at both ends thereof and has a longitudinallslot I2. in the'wall thereof. rA plunger' I3 is adapted to be inserted'through the open louter end' I4 of the tube for engagement with the: outerendof a'series of'ri'vets previouslyfplaced inthe tube. The plunger I3 'has a lug I5 .whichiprojects through the slot I2and is movable ytherealong,k A- tension spring I6. is 'con-Y nected' withA the lug vI5 tand. constantly. appliesv a pullingforce tothe. plungerlcausing the latter tor-advanceV thelrivetswl Lalong .the itubei I 0' to ward the inner-ori'deliveryend:I'Il thereof; 1

Adjacent its innerfordeliv'ery end the Ltube I0 hasa bracketfl ,soldered or otherwisexedly mounted thereonl? rThe bracket 'I 8 .preferably has a portion. I8afsurrounding Vor partially surrounding the. tube I0. and a pair of spaced ears I8band I8c projectingsubstantially radially of the tube. The ears vIiib and ylcrform ai'supportrfor anV elongated' hollow cover '19. which is adaptedto bereleasably held in closedr positionadjacent the vtube I0 bya spring clip 20 whichis carried 'by the coverv and engageable with the tube adjacent Aits outer end.v The cover IB'is' connected with the' ears I8b and AI8c by meansofa transverse hinge pin 2| which permits the cover tolbe swungtowardior` away from .the tube I 0; Between the ears IBbvand Iiic, there is provided a `grooved roller orsheave-22 Awhich issrotatably mounted onV the hinge pin 2|; "The tension springlt4 extends around `the grooved roller "22 andA longitudinally withinthevhollow cover I9. .The outer endof the-tension spring lIiiis suitably anchored to the cover rIII 'as4 by providingV thereon an integral'lug or tang 23v to which the outer end of the spring isconnected. l f s' .The rivets- IYI .are releasably retained in .thez'tube I0 by a Vplurality of resilient-fingers -2`5'which are disposed relative tothe delivery end4 II to engage v of the tube toward the work 21 into which a rivet is to be inserted, the inner or delivery end of the tube engages the converging portions of the resilient fingers 25 and spreads the same apart to relase the endrnost rivet from the tube and permit such rivet to be projected into the work opening 28 by the force of the tension spring I6,

For use in producing, the relative axial movement betweemthe-tube l'I 0 and the sleeve 26Ipro.- vide the sleeve with thrust means which projects beyond the resilient ngers and, in this instance. is in the form of a pair of integral axially extend'- ing arms 29. The arms 29 are engageable; with,A the surface of the work 2'I and serve to hold the free ends of the resilient lingers'2fzinlspacedref` lation to the work so that they can be` readily' spread apart by the delivery end I'I of the tube Without scraping on the worlcisurf'ace;v 'Iheztlirustz members 29 preferably have laterally extending.

Although thef sleeve.- 261 and the deliveryY end!

When additional rivets are to be inserted into the tube I0 the plunger I3 can be removed through the open end I4 by stretching the spring I6 as indicated in construction lines in Fig. 2.

InA Figs. l and 5 I show a modied form of my rivetfeedingl device iniwhich the: thrustmernbers 36' are not formed integral with the sleeve 31 carrying thel convergent resilient fingers 38 but are carried by a ring 39 surrounding the delivery en'd 40 ofthe tube 4I and lying Within the annular group of resilientl fingers. The sleeve 31 isk contracted Vas shown in Fig. 5 to form an annular shoulder"v 42 which is engaged by the ring 39A to enable the thrustmembers 36 to hold the ends oftheiresilientngers 38 in spaced relation to thesurface of the work 43. In inserting a rivet into the lWork opening 44 the tube 4I is moved toward the .-workandwithin-me sleeve-.31 andring 39fsofas; tti-cause; the-.convergentportions of the resilient-fingers to be; engaged-.and spread apart bystheg-delivery end- '4G-oi. the-tube thereby-releas- .ingr` the; endmost, rivet .inthe; manner already'- explained above. The sleeve.- 3.1- andl thering,.- 39 are: retainedonv the` deliver-yf endvl of'. the. tube: by the; resilient-.latch'- 45.- of'.- the bracket. 46.

Inf themodified form of. rivet.- feeding device shown-.in-.Figsx fiand 7 the-.delivery end Eil-of-,the tube 5I is movable in a sleeve'5f2- for enga-gement of-I suchl delivery-.endwiththe-convergent resilient ngerSi-Smcarried bysuclrsleeve. In this, for-m of the device .thel thrust: member which engages. the Work'. is.. in; thee form; of a; hollowtip f 54 formedof plastic or. any other" suitable. materialL and'. which surrounds the sleeve 52 and houses the resilient lngersi 53.

The. convergingZ end of.A thef tip.- 54 is. desirable. because it reduces the area of; the-tip: adjacent the surface@ of;l the. work- 58 1 and.- affordsI betten vision. of., thev Work opening and:- facilitates the.- insertionof. the stem of the rivet. thereinto.' As.` show-n in Fig.. 6, the. tip 54 hasv a; flangeon shoulder; 5.9 thereon adaptedto be engaged-.byfa resilientiarm. fof. thebracket-.BI for preventing. unintentional. separation of' the tipiromthe delivery end` of. thetube.

In Figs. 8 and 9 another modlcation ofithe invention. is illustrated which is similar toA the for-m. illustrated in Figs. 6 and- 7 but inI which the hollow tip 65' is retained on" the delivery-end v$6 of. the tube6'I by providing the tip with an axially extending slot' orV recessn 68 in Whicha resilient arm or; latch:l 69' engages: The latch 69v is carried byv theear' 16"' ofv the: bracket T-l. rI-'he companying drawingsiit: will'. now: be4 readilyunsd'ersto'od'f that.` If' have provided: improved rivet fingers.

feeding devices with which rivetsor the like can be easily and rapidly inserted into work open. It will be seen also that the novel means ings. provided for the releasing of the individual rivets from the device is not likely .to become jammed or to cause marring ofthe surface of the work.
